Hey guys,
Just got a brand new VA36 / g36c. Before ever using it, I switched to a longer tightbore (angry gun 6.03 407mm). It is double feeding nearly every shot. Most bb's dribble out of the barrel, a few will shoot below 100 fps (.28 bbastards). It's the stock hop up rubber, using a nub cut from a BIC pen just because
Have taken it apart and put it together multiple times with no change. Also tried several different mags.
Forgot to mention, the above is relative to semi auto. On full auto nothing happens. Remember, it's brand new, so doubtful that anything is worn out.
Thanks!
